SIGNIFICANT ACCOUNTING POLICIES (Policies)	Jun. 30, 2025
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The financial statement has been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and the instructions to Form 10‐Q. The Fund is an investment company for the purposes of accounting and financial reporting in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946, Financial Services – Investment Companies (“ASC 946”). The financial statement, including these notes, are unaudited and exclude some of the disclosures required in audited financial statements. Management believes it has made all necessary adjustments (consisting of only normal recurring items) so that the financial statement is presented fairly and that estimates made in preparing its financial statement are reasonable and prudent.
Use of Estimates	Use of Estimates The preparation of the financial statement in conformity with U.S. GAAP requires management to make assumptions and estimates that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statement. Management’s estimates are based on historical experiences and other factors, including expectations of future events that management believes to be reasonable under the circumstances. It also requires management to exercise judgment in the process of applying the Fund’s accounting policies. Actual results could differ from these estimates and such differences could be material.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist principally of cash and/or short term investments (overnight bank investments) which are readily convertible into cash and have original maturities of three months or less.
Organizational and Offering Costs	Organizational and Offering Costs Organizational and offering costs will only be borne by CPEP when CPEP first accepts third-party investors and begins investment operations and activities (“Initial Closing”), at which time, costs associated with the organization of the Fund will be expensed as incurred. Costs associated with the offering of each of the Fund’s classes of units as described in Note 5, Net Assets, will be capitalized as a deferred expense and included as an asset on the Statement of Assets and Liabilities and amortized over a twelve-month period from incurrence. As of June 30, 2025, third party investors have not been accepted and investment activities have not yet commenced, therefore organizational and offering expenses are not recorded in the accompanying Statement of Assets and Liabilities.
Income Taxes	Income Taxes No provision is made for federal, state, foreign or local income taxes, as income and losses are allocated to the individual shareholders who are responsible for reporting such and paying any taxes thereon. The Fund anticipates filing its initial tax return during 2026. There were no income taxes incurred by the Fund for the quarter ended June 30, 2025.

Disclosure of accounting policy for income taxes, which may include its accounting policies for recognizing and measuring deferred tax assets and liabilities and related valuation allowances, recognizing investment tax credits, operating loss carryforwards, tax credit carryforwards, and other carryforwards, methodologies for determining its effective income tax rate and the characterization of interest and penalties in the financial statements.
